Have you ever wanted to charge your cell phone, but didn’t want to waste precious electricity that you had to pay for? Well now you can get some exercise AND charge your phone for free, because good ol’ Nokia just came out with a bike phone charger!

How do I Charge my Phone with a Bike?

The Nokia Bicycle Charger Kit is attached to your bicycle. As you pedal your bike, it powers a small generator that transfers electricity to a charger on your handlebar. Voíla, just that easy.

How Much Pedaling To Charge Cell Phone?

I’ll let Nokia answer this question; Nokia, the floor is yours:

“To begin charging, a cyclist needs to travel around six kilometers per hour (four miles per hour), and while charging times will vary depending on battery model, a 10-minute journey at 10 kilometers per hour (six miles per hour) produces around 28 minutes of talk time or 37 hours of standby time. The faster you ride, the more battery life you generate.”

That sounds pretty good to me. Plus, it only costs around $20. So if you’re down for biking and charging your cell phone at the same time, this might just be the ticket for you.
